About us


A company with a history

For more than 60 years REDUR has been developing and manufacturing  instrument transformers, transducers and measuring instruments.  Our products are suitable for the most different and demanding applications. Established in 1963 as Elektro-Apparatebau Friedberg GmbH, the company was integrated in the Reten Group in 1975 and renamed Reten Messwandler GmbH. The present name REDUR goes back to the year 1988 when the company was renamed Reten Messwandler Düren. After the company was relocated in 1998 to Merzenich, near Düren, the first syllables of the company name and the city were used to coin the name REDUR. Today the company is located in Niederzier, a municipality between Cologne and Aachen.
